Common damage to mini RC cars
15 Nov 2017
The general damage to mini RC cars, especially those circulating in Indonesian, is seen from its packaging mostly written Made In China, from expensive to cheap.
Types and brands are diverse though for the electronic circuit is almost the same. Here I will discuss about the problems that often occur against some types of RC cars, especially the small size and low price.
Some of the damage that often happens to the RC car there that we can fix itself and there must be to the experts. Based on experience, I will try to summarize what kind of damage and tips to fix it, here's the description.
1. If the total die checks the line voltage of the battery, switch, cable installation.
2. If you can not turn left please check the output path of IC number 6 legs should have a voltage out if there is no we can replace the IC. Number 6 leg voltage exists, check the output transistor (Tr 9014), if not out, replace the transistor. Also check the dynamo drive transistor (there are 4 pieces) replace if any are dead.
3. Can not turn right to the same way as point 2 only different paths examined the leg IC voltage number 7 and so on.
4. The car can not back off, check the IC output voltage of the leg number 10 if there is no replace IC. If there is please check the output voltage of transistor 9014.
Replace the transistor when the voltage does not come out, check also 4 pieces of dynamo drive transistor (tr 8050 and tr 8550 respectively two pieces).
5. If you can not go forward you check the IC output voltage of leg number 11 and the same as step number 4 how to check it.
If a large size car uses turbo mode to increase speed, check the output section of IC IC number 12, the relay drive transistor (tr 9014) and the relay itself.
6. RC car running halt-slow, slow, check the battery and also check dynamo especially brush and connector (usually worn)
7. Reach remote of the car not far can check the receiving antenna part is still firmly in position? Remote battery still good? check the remote antenna as well, replace the battery remote if the voltage runs out, then at the receiver checks resistor-shaped windings are usually green with multitester broken or not.
Similarly, about the damage that is common in mini RC cars, for other tips I've discussed in previous articles and much more that we will review later. If this article useful please share and follow my blog, umpteen and thank you.

Damage to Receiver or RX circuit
This circuit usually uses an existing 16 pin IC that uses 8 pins. Actually the same function is just different pin output location only1. If the total die checks the line voltage of the battery, switch, cable installation.
2. If you can not turn left please check the output path of IC number 6 legs should have a voltage out if there is no we can replace the IC. Number 6 leg voltage exists, check the output transistor (Tr 9014), if not out, replace the transistor. Also check the dynamo drive transistor (there are 4 pieces) replace if any are dead.
